There is a book called "David N. Johnson Trumpet Tunes for Organ." Augsburg Fortress 2002. I don't remember if I got it from the OHS store or one of the other music sellers. Maybe Sheet Music Plus, since I buy from them. Check them out and see who has it. It has all the trumpet tunes including that one and another one in A.
This is where I bought them. I do not recognize that specific tune, but it has been a long time since I've played anything from the book. Also, mine has a different cover than shown, so it may not be the same thing.
